Sorting
Let's say that I have a database that I call part ID. This database has the following grouping:

Code:
Dart1=4
Dart2=8
Dart3=12

Fork1=68
Fork2=72
Fork3=64

Bike1=28
Bike2=24
Bike3=20

Car1=44
Car2=40
Car3=36

I want to write a program that would read this database and tell me when the 3rd item of each group is smaller than the second item of the same group or when the 1st item is greater than the 2nd item of that group. Basically item1 < item2 < item3 is the standard within the same group. If this is not met within that group, The script would print the output of all the groups that are different. For example, the output would be:
Code:
Fork1=68
Fork2=72          
Fork3=64

Car1=44
Car2=40
Car3=36

Any suggestions will be appreciated!

Thanks!

One way to do it with Perl -

Code:
$ 
$ cat f9
Dart1=4
Dart2=8
Dart3=12

Fork1=68
Fork2=72
Fork3=64

Bike1=28
Bike2=24
Bike3=20

Car1=44
Car2=40
Car3=36
$ 
$ perl -lne 'BEGIN {undef $/} while (/(\w+\d=(\d+)\n\w+\d=(\d+)\n\w+\d=(\d+))/sg) {print $1,"\n" if $2>=$3 or $3>=$4}' f9
Fork1=68
Fork2=72
Fork3=64

Bike1=28
Bike2=24
Bike3=20

Car1=44
Car2=40
Car3=36

Tyler,

Your script works. But I still have some issues. After I ran my surveys, my output file is as follows:
F
Code:
ork,1,68
Fork,2,72
Fork,3,64

Bike,1,28
Bike,2,24
Bike,3,20

Car,1,44
Car,2,40
Car,3,36

I used this sed command
Code:
sed -e 's/,/./' -e 's/,/=/' filename >> SW1_filename2


to make it look like this
Code:
Fork1=68
Fork2=72
Fork3=64

Bike1=28
Bike2=24
Bike3=20

Car1=44
Car2=40
Car3=36

However it won’t do it. With the commas in the format, your script does not work; with the equal sign, it works. Any idea what I am doing wrong?

Disregard my previous posting. I mistakenly enterer a comma instead of a semicolon. That's why it was not working.

Thanks!

Now, if you could explain the script to me, that would help. I need to modify it somehow. Basically what I am trying to do is to the following:
The output data for all the groups has 6 entries.But while most of the groups has only three entries filled, some groups have all 6 entries filled. What I want to do is Whenever the script reads the file and sees a group with only 3 entries filled, it needs to print the three rows that have data but strip the other three empty rows; for the groups with 6 entries filled, it just needs to print them out. That would be fantastic if you or someone else could help.


Thanks!

Hey rdcwayx,
I tried your script but got this error message.
Code:
awk: record `1.3=12
1.2=348
1.1=180
...' too long

For your info, my input file format was as follows:
Code:
554.3=432
554.2=264
554.1=96
555.3=452
555.2=284
555.1=116
556.3=488
556.2=320
556.1=152
557.3=340
557.2=172
557.1=4
558.3=356
558.2=188
558.1=20
559.3=108
559.2=276
559.1=444

Keep in mind that this represents a fraction of a huge database.

Let me know what you think.

Thanks!

...
Firstly, the Perl one-liner posted earlier will *not* work for groups of 6 lines. It works *only* for groups of 3 lines.

Secondly, it may be beneficial if you could post some test data for groups of 3 lines as well as 6 lines. And post the output as well that shows what exactly is to be done for each group.

The input you've posted above is difficult to comprehend because it does not have the blank line that separates one group from the other.

Okay, I have 6 groups. Now I want the script to go through these groups and look at the structure of each group. If the .1 (within a group) is greater than the .2 or .3 OR if .2 is greater than .3 within a group; thus output these groups. In our case the output would be groups.

input file
Code:
1.6=176
1.5=172
1.4=168
1.3=14
1.2=13
1.1=12

230.3=146
230.2=147
230.1=148

3.3=20
3.2=19
3.1=18

5.6=166
5.5=122
5.4=160
5.3=103
5.2=102
5.1=100

100.6=176
100.5=172
100.4=168
100.3=20
100.2=12
100.1=16

117.3=24
117.2=82
117.1=79

Output file
Code:
117.3=83
117.2=82
117.1=79

100.6=176
100.5=172
100.4=168
100.3=20
100.2=12
100.1=16

230.3=146
230.2=147
230.1=148

I hope it is clear enough.
